TYPE-CASTING MACHINE.

structed, comprise a part or mold providing the matrix of the desiredtype character and designed to close the orifice through which themolten metal is injected; and such mold must be located in acarefully-defined position with regard to stationary parts of themachine in order to cast the characters in correct position withrelation to the edges or side faces of the type block. This is necessary in order to efi'ect a true alinement and an even spacing of thecharacters relative to each other when used for printing.

Therefore, when a given type character is to be cast, the operator isrequired to adjust the position of the mold in two. direc tionsperpendicular to each other for the purpose of insuring the arrangementof the character at the same distance from the lower edge 01"? the typeblock and at the proper distance from both side edges of the type block.

in the present practice, this operation is effected each time a givencharacter is to be cast, and the correct position oi the mold is onlyobtained experimentally; obviously such an operation isv of long anddifficult character, and requires careful attention on the part of theoperator.

According to my invention, the drawbacks above referred to are removed,the mold holder being adapted to be adjusted in two directionsperpendicular to each other by means of micrometer screws provided withgraduations or verniers which give a true indication of the position ofthe holder and of the mold or matrix with relation to stationary partsof the machine.

In the accompanying drawings, which show by way of example oneembodiment of the mold holder according to the invention, Figure 1 is avertical section of the device along its longitudinal axis; Fig. 2 is aplan view thereof; Fig. 3 is a transverse section on line 33, Fig. 1;and Fig. 4L is a front view of the device.

As shown in said drawing, the device comprises a bracket 1 adapted to besecured on the casting machine at the place of the usual Specificationof Letters Patent. Patented Sept. 14, 1920.

mold holder; and on this bracket there is mounted for vertical slidingmovement a support 2 which is. connectedtherewith by means of a boltWhose head 8 engages the bracket, the bolt being secured to said bracketand passing through a slot 5 formed in said support 2.

In the body of bracket 1 is journaled a vertical spindle 6 having amilled operating head 7 and a screw threaded portion 8, the latterengaging a nut 9 attached to support 2 by screws 28. The lower end ofspindle 6 abuts a ainst an adjustin screw 29 locked in position by ascrew 30.

The spindle 6 may be rotated by manipulating head 7 for the purpose ofadjusting vertically the support 2, the nut 9 attached to said supportbeing operated by the screwthreaded portion 8 of said spindle. By givingthe proper pitch to said scre v 8 (say, a pitch of one millimeter) andby providing suitable vernier scales on adjacent stationary and movableparts of the device (for instance, on a liange7 formed integral withhead 7 and on a sleeve 1 integral with the bracket 1, or on an edge ofthe support and on the adjacent edge of the bracket 1) it is alwayspossible to take an accurate reading of the indications defining thecorrect position of the support in the vertical direction, the saidscales being preferably. graduated in hundredths of a millimeter.

The indications which have been found by attempts in the describedmanner in connection with a given type character are suit ably recorded,and'then the device may be easily and truly adjusted at any time forcasting the same character with even side spaces, the character beingarranged, as usual, with its vertical axis erpendicular to the axis ofspindle 6 (see ig. 4).

A slide 10 is mounted to move on support 2 in a direction perpendicularto the axis of spindle 6 and parallel with theface of the type, saidslide being provided with jaws 11-11 having projections 1l11 adapted.

to grasp the mold or matrix 12. A nut 13 or equivalent part formedintegral with the slide 10 engages the threaded portion 1 1 of a spindle15, which'is journaled in support 2 by means of a bushing 32. Thisspindle 15 is provided at one end with a milled head 16 havinggraduations thereon to show the true position of the spindlecorresponding with a given position of the matrix or mold 12, so that bymanipulating said head 16, the

mold or matrix 12 may be shiited into proper position to bring the loweredge of the type character the desired distance from the lower edge ofthe type block. The screw thread of spindle 15 preferably has a pitch ofone niillin'ieter, and the head of said spindie is graduated intwo-hundredths of a millimeter.

l. or the purpose of locking the parts of the d "ice in the desiredposition, the bolt connecting support 2 with bracket 1 is provided atits rear end with a nut 17 which may he manipulated to clamp the bolthead 3 arai st the support 2 and, hence, the latter g nst the brael:it 1. The support 2 is also provided with a bolt 18 passing through aslot 31 in slide 10 and having a nut 19 adapted to clamp said slide 10in the required position on support 2.

The device is provided with suitable means for holding the mold matrix12 in requircd position. in the construction illustrated, a knownarrangement is shown com.- prisin a stem 20 adapted to engage slotsprovided on the rear face of the matriX 12 to clamp it against theprojections 11 on jaws 11, said stem being connected with a springplunger (not shown) mounted in a drum 21 and operated by a handle 22,The pressure of the spring causes the stem 20 to bear against mold 12and to force the same against projections 11.

The device is mounted on the casting machine in such a manner as to havethe mold 12 located in front of the stationary block 23 in which isirorided a recess 24c forming the mold for the type bloc-h; said recesscommunicates through a port in the plate 25 with the nozzle 25 of thcrucible 27 con taining the molten metal.

By the described device the matrix or mold 12 may be carefully adjustedin correct position for each type character by manipulating heads and 16so as to locate the 4 character at the proper distances from the lowerandside edges of the type block, these edges being d lined by thestationary part The indications shown by the graduations on the vernierscales, and defining the true position ol the matrix, may be read andrecorded so that when it is desired to reproduce the same character, theheads 7 and 16 may be easily turned to the required position for thetrue adjustment of the matrix 12 without again necessitating long andcareful manipulations.
